The application provides a data scheduling method and device and electronic equipment. The embodiment automatically identifies a cold unit memory (referred to as a cold unit memory) in a first memory, whose access frequency per unit time is less than a first set threshold, and a hot unit memory (referred to as a hot unit memory) in a second memory, whose access frequency per unit time is greater than or equal to a second set threshold, automatically schedules data in the hot unit memory in the second memory to move to an idle unit memory in the first memory, and automatically schedules data in the cold unit memory in the first memory to move to an idle unit memory in the second memory, so that data with high access frequency is stored in the local first memory of the system, and data with low access frequency is stored in the second memory which is expanded, the advantages of local memory high-speed access and memory capacity expansion are maximized, and the data access efficiency is improved.

Provided in the present application are a data scheduling method and apparatus, and an electronic device. In the embodiment, a unit memory (which is referred to as a cold unit memory), an access frequency per unit time of which is lower than a first set threshold, in a first memory and a unit memory (which is referred to as a hot memory unit), an access frequency per unit time of which is greater than or equal to a second set threshold, in a second memory are automatically identified, data in the hot unit memory in the second memory is automatically scheduled and migrated into an idle unit memory in the first memory, and data in the cold unit memory in the first memory is automatically scheduled and migrated into an idle unit memory in the second memory, such that data with high access frequency is stored in the local first memory of a system, and data with low access frequency is stored in the extended second memory, so as to maximize the advantages of high-speed access performed by means of a local memory and memory capacity expansion performed by means of an extended memory, thereby improving the data access efficiency.

In an image forming apparatus, an image forming unit can be replaced. An outer cover becomes in an open status when the image forming unit is replaced. An inner cover becomes in an open status with a manual operation with taking a predetermined time after the outer cover becomes in an open status when the image forming unit is replaced. A cover open / close sensor detects open and close statuses of the outer cover. The image forming unit includes a non-volatile unit memory. Further, the controller (a) performs data communication with the unit memory, and (b) if data communication with the unit memory is ongoing when the cover open / close sensor detects that the outer cover becomes in an open status, completes the data communication and cuts off power supply to the image forming unit before the predetermined time elapses.
